How to Build a Wet Wall, Part 3 How to Build a Wet Wall, Part 3

What You'll Need
Building Inspector
Ready Mix Cement
Cement Fiber Board
Pipe Hangers

When building a wet wall you will need to follow a few different local building codes in order to make sure it is done safely and correct. By following the last two sections of this series of articles you should have your drain pipe and wet wall framed in. The pipes should be in place and you are now ready to finish off your wet wall and complete your new bathroom. Before you do that, there are a few more steps that need to be taken.

Step 1: Finish off Pipe Installation

After you have all of the pipes in position you will need to finish off the installation by securing them with pipe hangers and supports. This will keep the pipes from rattling, banging, and being damaged. Once the hangers are connected then you can call for an inspection.

Step 2: Have Building Inspection

Before you can legally move forward with your wet wall, and bathroom installation, you need to have an inspection completed. You should not worry about the inspection as they will give you plenty of tips, and how to fix something if anything is wrong. However, if you followed the steps in this series, there should not be any problems.

Step 3: Install Vapor Barrier

Because this is a wall that has all of the water pipes secured within it, you will need to protect the wall covering from any of the humidity of the pipes. A vapor barrier should be attached over the studs. This can be a basic plastic covering that is attached through staples.

Step 4: Install Wall Covering

There are two ways to be able to cover the wet wall. You can use a heavy cement fiber board that will be able to stand up to the moisture, or you can use drywall. The vapor protection should keep the drywall from being ruined from any moisture caused by the water pipes. However, if you want more protection, the cement board is the solution.

Step 5: Measure, Cut, Secure

No matter which type of covering you choose, you will have to follow the same procedures. Measure for the length that you need, mark the lines on the board, or drywall, and score it with a utility knife. Run the knife a few times over the mark and the covering will then break in a fairly neat line. Attach to the studs with the appropriate screws.

Step 6: Finish off Wet Wall Covering

If you chose to use fiber board for the covering you will need to use a thin layer of mortar over the seams and screw holes. If you used drywall, then you need to use tape and drywall spackle. Spread it out in a thin layer and sand it smooth.

Step 7: Fill in Trench

Once the wall has been completed you can turn your attention to the trench in the floor. Clean up as much as you can all of the debris. Mix up some ready mix concrete in a wheelbarrow and begin spreading it out along the trench. Work quickly so that you do not try to merge wet cement with dry cement. Use trowel as you work to smooth out the finished floor.
